What is a split system air conditioner?

A split system air conditioner is a refrigerative air conditioner that divides its components into two segments: an indoor unit –which contains the evaporator compartment and the outdoor unit –which contains the condenser and compressor units. The condenser serves to expel unwanted heat located in the inside unit. Both units are linked by insulated conduits, passed through a small hole in the wall. Split system air conditioners are relatively quiet and are easy to install (by a qualified technician) and that is why they are so popular in NSW. They are also very convenient to handle, usually via an infrared remote control.

Where can I install split system air conditioners?

It is difficult to identify the ideal location in the house to install these units as there are different sizes and capacities available. However, there are some basic considerations about where to mount a split system.

Indoor unit positioning

The indoor system should be installed in a central location in the room you wish to cool to allow for evenly distributed air flow throughout the area. Visualise how the room is going to look like after the system has been installed. If it’s going to be set in a bedroom, then it’s best to install it above the bed.

Indoor units should be placed high up the wall to ensure that the air is blown throughout the room. At the same time, it should still be within reach when you want to clean it. Ensure that the unit is not installed directly above electrical fixtures.

All this also needs to take into account what is running on the inside and outside of the wall in which you wish to install it – seek professional advice.

Outdoor unit positioning

The licensed technician will pinpoint the best place to install the outdoor unit. It should be mounted on stable places where it will not wobble, with ample space on either side to allow the flow of air. Also ensure that it is not placed close to corrosive agents and if possible, not in direct sunlight (this will assist with energy efficiency and general function in the heat of summer).
